3. Question

What is a helix?

A helix is a curve made by a point moving around a cylinder and the distance of the points moves parallel to the cylinder axis and is proportional to the angle of rotation around that axis.
A helix is a straight line made by a point moving around a cylinder and the distance of the points moves parallel to the cylinder axis and is proportional to the angle of rotation around that axis.
A helix is a curve made by a point from top to bottom of a cylinder and the distance of the points moves parallel to the cylinder axis and is proportional to the angle of rotation around that axis.
A helix is a curve made by a point moving around a cylinder and the distance of the points moves unparallel to the cylinder axis and is proportional to the angle of rotation around that axis.

Question 6 of 10

6. Question

What is the integral of x² ex dx?

f(x) = x² d g(x) = ex dx df (x) = 2x dx g(x)= d g(x) = ex dx = ex
f(x) = x² d = ex dx df (x) = 2x dx g(x)= d g(x) = ex dx = ex
f(x) = x² d f(x) = ex dx df (x) = 2x dx g(x)= d g(x) = ex dx = ex
f(x) = x² d g(x) = ex dx df (x) = 2x dx g(x)= d f(x) = ex dx = ex

Question 7 of 10

7. Question

If a coin is tossed five times, what is the probability of getting at last one tail?

p(at least 1 tail) = p(1 tail) + p(2 tails) + p(3 tails) + p(4 tails) + p(5 tails) = 1-(0.5)5 =0.96875
p(at least 1 tail) = p(1 tail) + p(2 tails) + p(3 tails) + p(4 tails) + p(5 tails) = 10-(0.5)5 =0.96875
p(at least 1 tail) = p(1 tail) + p(2 tails) + p(3 tails) + p(4 tails) + p(5 tails) = 0.5-(0.5)5 =0.96875
p(at least 1 tail) = p(1 tail) + p(2 tails) + p(3 tails) + p(4 tails) + p(5 tails) = 1-(0.5)5 =1.96875
